The suitability of N2 to replace SF6 in a triggered spark-gap switch for pulsed power applications [PDF]

, 2009
The high dielectric strength of sulphur hexafluoride (SF6) when compared with other gases, coupled with safety benefits such as non-flammability and non-toxicity, has seen the widespread use of SF6 for the insulation of switching components. However, SF6

Fossil Hegemony and Capitalist Realism in Tropic of Orange

Future Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This article examines Karen Tei Yamashita's Tropic of Orange (1997) through the lens of Mark Fisher's influential concept ‘capitalist realism’. Scholars of petrofiction have pointed to a political ambivalence in the representation of fossil fuels, where a better understanding of fossil capital can overwhelm as much as galvanize.

Analysis of Arc Re-Ignition in Vacuum Interrupter-Based HVdc Circuit Breakers

IEEE Access
The protection of HVdc systems has long been challenged by the absence of natural current zero-crossing, typically addressed using L-C branches. However, the phenomenon of multiple arc reignitions in vacuum interrupter (VI) based HVdc circuit breakers ...

Pressure estimation in vacuum circuit breakers

IEEE Transactions on Dielectrics and Electrical Insulation, 1995
The pressure of vacuum switching elements after production is checked normally by Penning or magnetron methods (combined electrical and magnetic field). Vacuum in the range of 10-1 to 10-4 Pa can be measured in this way. After assembly into circuit breakers however, these methods are not applicable. HF interruption performance during the make operation

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors

Advanced Science, Volume 13, Issue 21, 13 April 2026.
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...
